A multicenter phase III prospective randomized trial of high-dose epirubicin in combination with cyclophosphamide (EC) versus docetaxel followed by EC in node-positive breast cancer. GOIM (Gruppo Oncologico Italia Meridionale) 9902 study.

BACKGROUND: The Gruppo Oncologico Italia Meridionale 9902 trial compared four cycles of high-dose epirubicin plus cyclophosphamide (EC) with four cycles of docetaxel (Taxotere, D) followed by four cycles of EC as adjuvant treatment of node-positive breast cancer. PATIENTS AND METHODS: Patients were randomly assigned to EC (E 120 mg/m(2), C 600 mg/m(2), arm A) for four cycles or four cycles of D (100 mg/m(2)) followed by four cycles of EC (arm B), both regimens every 21 days. Hormone receptor-positive patients were given hormonal therapy for 5 years. Primary end point was 5-year disease-free survival (DFS). Secondary objectives were overall survival (OS) and safety. RESULTS: There were 750 patients enrolled. With a median follow-up of 64 months, 5-year DFS was 73.4% in both arms, and 5-year OS was 89.5% versus 90.7% in arm A and B [hazard ratio was 0.99 (95% confidence interval for DFS 0.75-1.31; P = 0.95)], respectively. Grade 3-4 toxicity was more common in arm B. CONCLUSIONS: This study did not show advantages from the addition of docetaxel to high-dose EC as adjuvant chemotherapy in node-positive breast cancer. The small sample size and low number of DFS events may have limited the ability to observe statistically significant difference between the two arms.

A multicenter phase II randomized trial of docetaxel/gemcitabine versus docetaxel/capecitabine as first-line treatment for advanced breast cancer: a Gruppo Oncologico Italia Meridionale study.

OBJECTIVE: To evaluate two docetaxel-based regimens as first-line treatment in advanced breast cancer patients. METHODS: Patients were randomly assigned to docetaxel/gemcitabine (arm A: docetaxel 75 mg/m(2) on day 1, gemcitabine 1,000 mg/m(2) on days 1 and 8) or docetaxel/capecitabine (arm B: docetaxel 75 mg/m(2) on day 1, capecitabine 1,250 mg/m(2) twice daily on days 1-14); both chemotherapy regimens were repeated every 21 days. The primary objective of the study was to evaluate the response rate. RESULTS: Seventy-two patients were enrolled (36 each in arms A and B). Responses according to intention-to-treat analysis were as follows: arm A, 41.7% [95% confidence interval (CI) 25.6-57.8]; arm B, 38.9% (95% CI 23-54.8). Median progression-free survival was 10.9 months (95% CI 8.1-13.7) in arm A and 10 months (95% CI 8.8-11.2) in arm B. Overall survival was 26 months (95% CI 22.0-30.0) in arm A and 28 months (95% CI 23.4-32.6) in arm B. Both treatments were well tolerated; myelosuppression was the dose-limiting toxicity, with grade 3-4 neutropenia in 13.8 and 19.4% of the patients in arms A and B, respectively. No relevant differences in other toxicities were observed in the two arms, except for diarrhea (13.9%) and hand-foot syndrome (11.1%), which occurred only in arm B. CONCLUSIONS: Both regimens were active and well tolerated in advanced breast cancer.

[High-dose CEF (cyclophosphamide, epirubicin, fluorouracil) as primary chemotherapy in locally advanced breast cancer: long-term results]. / CEF (ciclofosfamide, epirubicina, fluorouracile) ad alte dosi come chemioterapia primaria nel trattamento del carcinoma mammario localmente avanzato: risultati a lungo termine.

PURPOSE: To determine wether primary CEF is effective in locally advanced breast cancer, as measured by response, local recurrences, disease free survival (DFS) and overall survival (OS). MATERIAL AND METHODS: From 1990 to 1998, 62 patients with stage III disease were enrolled into a prospective study at Regina Elena Institute for Cancer Research, Rome. Inflammatory breast cancer (IBC) was included. Patients received three 21 days cycles of chemotherapy that consisted in epirubicin 50 mg/m2, cyclophosphamide 400 mg/m2, and fluorouracil 500 mg/m2 i.v. on days 1 and 8. G-CSF (300 microg) was given subcutaneously every other day from day 5 to day 17. After primary chemotherapy, whenever possible, mastectomy or conservative surgery was performed. Subsequently responding patients received the same regimen, while non responders were given a non cross resistant chemotherapy. In case of conservative surgery or initial T4 tumor radiation therapy was performed at the end of adjuvant chemotherapy. ER positive patients received tamoxifen 20 mg/d for five years. RESULTS: Seven IIIA patients had a median OS of 43 months (C.I. 95%, 31-55) and DFS of 42 months (C.I. 95%, 16-68), while 15 IBC patients had a median OS of 52 months (C.I. 95%, 52-79) and DFS of 27 months (C.I. 95%, 14-39). Forty IIIB non inflammatory breast cancer patients had a median DFS of 87 months (C.I. 95%, 1-175); median OS was not reached. Ten-year OS was 28.6% for stage IIIA, 50.6% for stage IIIB and 36% for IBC. CONCLUSION: Primary CEF appear to be an effective treatment. In our study we obtained a good local control and interesting long term data of disease free and overall survival.

Targeting immune response with therapeutic vaccines in premalignant lesions and cervical cancer: hope or reality from clinical studies.

Human papillomavirus (HPV) is widely known as a cause of cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). HPVs related to cancer express two main oncogenes, i.e. E6 and E7, considered as tumorigenic genes; their integration into the host genome results in the abnormal regulation of cell cycle control. Due to their peculiarities, these oncogenes represent an excellent target for cancer immunotherapy. In this work the authors highlight the potential use of therapeutic vaccines as safe and effective pharmacological tools in cervical disease, focusing on vaccines that have reached the clinical trial phase. Many therapeutic HPV vaccines have been tested in clinical trials with promising results. Adoptive T-cell therapy showed clinical activity in a phase II trial involving advanced CC patients. A phase II randomized trial showed clinical activity of a nucleic acid-based vaccine in HPV16 or HPV18 positive CIN. Several trials involving peptide-protein-based vaccines and live-vector based vaccines demonstrated that these approaches are effective in CIN as well as in advanced CC patients. HPV therapeutic vaccines must be regarded as a therapeutic option in cervical disease. The synergic combination of HPV therapeutic vaccines with radiotherapy, chemotherapy, immunomodulators or immune checkpoint inhibitors opens a new and interesting scenario in this disease.

Phase III randomized study of fluorouracil, epirubicin, and cyclophosphamide v fluorouracil, doxorubicin, and cyclophosphamide in advanced breast cancer: an Italian multicentre trial.

From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

Intrapatient comparison of single-agent epirubicin with or without lonidamine in metastatic breast cancer.

The aim of this study was to determine if lonidamine (LND) supplementation to single-agent epirubicin (EPI) could reverse anthracycline resistance in patients with metastatic breast cancer. 45 patients with metastatic breast cancer were treated with EPI 120 mg/m2 by intravenous (i.v.) bolus every 3 weeks. Patients who progressed were given the same chemotherapy regimen on day 4 in combination with oral LND, 150 mg on day 1, 300 mg on day 2 and 450 mg on days 3-5. Among the 40 evaluable patients, 6 complete responses (CR) and 14 partial responses (PR) were achieved with EPI treatment alone for an overall response rate of 50%. The median duration of response was 6.5 months. Among the 25 patients treated with EPI+LND, 5 PR (21% of 24 evaluable patients) were observed with a median duration of response of 7 months. The median survival in patients receiving both treatments was 20 months. The survival for all patients was 18 months. The survival of patients receiving LND was not significantly longer than for the other patients. Myelotoxicity was the most common side-effect followed by alopecia, nausea and vomiting, and stomatitis. LND-related toxic effects were mild-to-moderate epigastralgia and myalgia. Anthracycline-related toxicity was the same in the two treatment groups. This study indicates that LND may circumvent clinical resistance to EPI without altering the pattern or severity of the toxicity of this anthracycline. Continued investigation of the clinical modulation of EPI resistance by LND in breast cancer is warranted, hopefully in patients with known multidrug resistance status.

Fluorouracil, doxorubicin, and cyclophosphamide versus fluorouracil, doxorubicin, and cyclophosphamide plus lonidamine for the treatment of advanced breast cancer: a multicentric randomized clinical study.

Experimental models have demonstrated the Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH)-potentiating activity of lonidamine. Phase II clinical trials on advanced breast cancer have shown that this drug induced a 16% objective response rate. Present multicentric randomized trial was conducted to verify whether lonidamine can potentiate the antineoplastic effects of conventional fluorouacil, Adriamycin, cyclophosphamide (FAC) chemotherapy in advanced breast cancer. From January 1987 to December 1989, 265 patients were enrolled in this study, and 231 are evaluable for response. After stratification according to institution and ECOG performance status (PS), the patients were randomly allocated to receive either standard FAC therapy (group A) or FAC plus lonidamine (600 mg orally daily three times a day) (group B). After three FAC courses, the patients with no progressive disease were further randomized to either receive continuous treatment up to the time of tumor progression (maximum: 10 courses) or to discontinue therapy when a response "plateau" was reached. In this latter group, the same therapy was restarted at relapse or disease progression. Objective response (complete response plus partial response) was significantly higher in group B (66.3%) compared to group A (42.3%). The actuarial median times to disease progression was also significantly longer (P less than 0.0001) in group B (median 9 months) than in group A (median 6 months). Other than myalgia and gastric pain, no increased toxicity was observed in the lonidamine. The analysis of second randomization are yet available because of the longer follow-up time required. Present findings suggest an interesting additive effect of lonidamine when combined with FAC chemotherapy and warrant further investigation in other therapeutic regimens and in other neoplastic diseases.

Combination chemotherapy with oral idarubicin and cyclophosphamide for metastatic breast cancer.

A group of 40 women with objectively measurable metastatic breast cancer was treated with idarubicin, 35 mg/m2 on day 1, and cyclophosphamide, 200 mg/m2 on days 2-5, both drugs being administered orally every 3 weeks. Of 37 evaluable patients, 4 (10.8%) achieved a complete response and 14 (37.8%) a partial response, for an overall response rate of 48.6% (95% confidence interval, 37.45%-59.75%). In previously untreated patients the response rate was 58.3%, whereas it was 44% in patients previously exposed to cytotoxic drugs. The median duration of response was 6.5 months, and the median survival of all patients was 10.5 months. Moderate nausea and vomiting were common. Diarrhoea, which occurred in 37% of the patients, was usually short-lived. Alopecia was generally mild, myelosuppression was the dose-limiting toxicity. Grade 3-4 leukopenia occurred only in pretreated patients. In previously untreated patients it was generally of grade 1-2. Laboratory evidence of cardiotoxicity (greater than or equal to 20% decrease in the left-ventricular ejection fraction from the baseline value) was observed in 3 out of 26 patients, who had at least two determinations of the left-ventricular ejection fraction, and was transient in nature. No cases of congestive heart failure were observed. These results indicate that the combination of idarubicin + cyclophosphamide represents a practical and effective regimen to be used in selected patients with advanced breast cancer.

5-Fluorouracil plus interferon alpha-2a compared to 5-fluorouracil alone in the treatment of advanced colon carcinoma: a multicentric randomized study.

Biochemical modulation is one of the most interesting fields in cancer chemotherapy. Interferon-alpha (IFNalpha) is a cytokine that is able to influence the pharmacodynamics of 5-fluorouracil (5FU) through a number of mechanisms. With the aim of confirming some data emerging from the literature, we initiated a multicentric randomized study comparing the combination of 5FU and IFNalpha-2a with 5FU alone in the treatment of advanced or metastatic colon cancer. A group of 205 colon cancer patients (104 in the 5FU arm and 101 in the 5FU + IFNapha-2a arm) were included in the final intention-to-treat analysis. Rectal cancers were not considered eligible. All patients had measurable disease, were aged 75 years or less, had a Karnofsky index of at least 60 and had good bone marrow, renal, liver and cardiac functions. No previous chemo-immunotherapy was allowed. The treatment was 750 mg/m2 5FU (4 h i.v. infusion) on days 1 5 and then i.v. bolus weekly, starting from day 12, with or without IFNalpha-2a given s.c. three times weekly (starting dose 3 x 10(6) IU rising to 9 x 10(6) IU, if tolerated). Patients were treated until progression or, if responsive, for a maximum of 48 weeks and then observed for a period of 2 years. The primary end-point of the study was objective clinical response (OR); secondary parameters were time to progression, overall survival, and time to death after progression. WHO criteria were used for both clinical response and toxicity measurements. Dose reduction was planned a priori in the event of significant toxicity due to 5FU, IFNalpha-2a or both. Association between primary and secondary end-points and treatment was studied by univariate and multivariate analysis. Altogether, 47 patients achieved a documented response. A 25% OR was observed in the combination arm while a 21% OR was seen in the 5FU arm; this difference is not statistically significant (P = 0.6). Patients with a small tumour burden (below 5 cm2) showed a higher probability of response in both arms. Patients in the experimental arm had a higher but not statistically significant cumulative progression-free probability. Median survival was 47.1 weeks overall, while it was 43.7 and 48.5 weeks in the control and experimental arms, respectively. The combination was clearly more toxic than 5FU alone, leukopenia being the most frequent side-effect in the experimental arm and nausea and vomiting in the control arm. In conclusion these results are quite disappointing and 5FU + IFNalpha-2a can not be considered a standard treatment for advanced colon cancer.

5-fluorouracil, adriamycin, and BCNU (FAB) combination chemotherapy for advanced gastric cancer.

Thirty-two evaluable patients with advanced measurable gastric adenocarcinoma were treated with a combination of 5-fluorouracil, adriamycin, and BCNU (FAB). Two complete and fourteen partial responses were observed, with an overall response rate of 50%. The median duration of response was 10 months, and the median survival of all 32 patients, 7 months. Responding patients had significantly better survival than the nonresponders (P less than 0.001). Analysis of the results according to pretreatment performance status, resectability of the primary tumor, and histologic differentiation of the malignancy demonstrates that only the first influenced the therapeutic results. The FAB regimen was well tolerated, allowing administration of nearly the whole of the projected drug dosages during the course of the therapy in all but three patients. These results indicate that the FAB combination is an effective chemotherapeutic regimen in metastatic or locally advanced gastric carcinoma. Incorporation of this regimen into the design of combined-modality treatment would result in improved prognosis.

Alternating combination chemotherapy of advanced soft tissue sarcomas in adults.

The possibility of improving treatment results using an alternating combination chemotherapy was explored in 40 evaluable patients with advanced soft tissue sarcomas. Treatment regimen consisted of adriamycin and DTIC alternating with vincristine, actinomycin D, and cyclophosphamide. Four patients achieved a complete response and eight achieved a partial response, with an overall response rate of 30%. The median duration of response was 14 months. The median survival time was 28 months for responders compared with 7 months for nonresponders (p = 0.001). Toxicity was predominantly limited to nausea, vomiting, and myelosuppression. Although this alternating regimen failed to improve response rates over other combinations, survival times observed in the present study should provide impetus to evaluate further the concept of sequential noncross-resistant combinations.

5-Fluorouracil, epirubicin, and BCNU (FEB) in advanced measurable gastric cancer.

Forty-eight patients with advanced measurable gastric cancer were treated with the three-drug combination of 5-fluorouracil, epirubicin, and BCNU (FEB). The response rate was 42% in 45 evaluable patients. There were five complete responders (11%). The median duration of response was 13 months, and the median survival of all patients was 9.2 months. Toxicity was generally mild to moderate. No instances of congestive heart failure were recorded. These results indicate that patients with metastatic gastric cancer can be effectively palliated with FEB chemotherapy.

Epirubicin in non-Hodgkin's lymphomas.

Epirubicin (Epi-DX), a new analog of doxorubicin, was administered I.V. once q 3 weeks at the dose of 90 mg/m2 to 20 evaluable patients with non-Hodgkin's lymphomas (NHL). Eighty-two percent of patients with favorable histology and 67% with unfavorable histology achieved complete or partial remissions, with an overall response rate of 75%. Gastrointestinal and hematologic toxicity was generally mild to moderate. Reversible ST-T changes were observed only in two patients. Epi-DX has high activity in patients with NHL, and further studies in combination with other agents are recommended.

Extravasation of contrast medium from cerebral aneurysmal rupture during angiography (remarks on four cases).

The authors report four cases of contrast material extravasation during carotid angiography from cerebral aneurysmal rupture. The thesis of a coincidental event not due to an increase in the intraarterial pressure, is supported. The poor prognosis of these bleedings, detectable on angiography, is underlined and the questionable toxic effect of contrast material in the subarachnoidal space is discussed.

Extracranial bleeding and extravasation of contrast medium after penetrating head injury. Case report.

The Authors report a case of extravasation from deep and small cerebral arteries associated with traumatic thrombosis of the left anterior cerebral artery following penetrating head injury. The rareness of this event is asserted. The event related to the hemorrhage extravasation are discussed.

Triple combination antimicrobial regimen in the treatment of infections of neutropenic cancer patients.

Twenty-six cancer patients (pts) with chemotherapy-related neutropenic fever were treated with vancomycin 30 mg/m2/day i.v. every 12 hrs, imipenem 1500 mg/day i.v. every 8 hrs, and pefloxacin 800 mg/day i.v. every 12 hrs. Twelve fevers of unknown origin (FUO), 10 gram-positive, 3 gram-negative and 1 mycoplasma were also treated. Globally, cure was observed in 22 pts (84%) and failure in 4 pts (16%); in gram-positive infections alone, cure was observed in 10 pts (80%) and failure in 4 pts (20%). Defervescence was obtained within 3 days in 77% pts. No relevant side effects were observed.

The integrated treatment of peritoneal carcinomatosis. A preliminary experience.

Some low-grade malignant tumors arising in the abdomen, lack of infiltrative attitude and "redistribute" on the peritoneum with no extraregional spreading. In this cases the complete tumor cytoreduction followed by intra- or postoperative regional chemotherapy has curative intent. Peritonectomy is the complete removal of all the parietal peritoneum and the visceral peritoneum involved by disease. After peritonectomy hyperthermic antiblastic perfusion is carried out throughout the abdomino-pelvic cavity for 60 minutes, at a temperature of 41.5 degrees C, with mitomycin C (3.3 mg/m2/Lt of perfusate) and cisplatin (25 mg/m2/Lt) (appendicular or colorectal primary), or cisplatin alone is (ovarian primary). Alternatively the immediate postoperative regional chemotherapy is performed with 5-fluorouracil (13.5 mg/Kg) and Lederfolin (125 mg/m2) (colic or appendicular tumor) or cisplatin (25 ng/m2) (ovarian tumor), each day for 5 days. Twenty patients affected by extensive peritoneal carcinomatosis (12 ovarian, 5 colonic, 1 appendicular, 1 mesothelial and 1 gastric primary) were submitted to peritonectomy with no residual macroscopic disease in all cases except three. Six patients were treated with intraoperative intra-abdominal hyperthermic antiblastic perfusion, while immediate postoperative intra-abdominal chemotherapy was given in 4 patients and systemic chemotherapy in other 5. Hospital mortality was 20%. At a mean follow-up of 11 months 14 patients are alive, 11 without disease and the median overall survival is 10.2 months. The curative potential of the combined therapeutic approach seems high in patients with peritoneal carcinomatosis from ovarian or colorectal primary not responding to systemic chemotherapy. Selection criteria of patients can strictly affect the surgical risk and the treatment has to be reserved for controlled clinical trials.

Recording of intracranial pressure and daily drainage in pseudotumor cerebri. A preliminary study.

After long-term recording of intracranial pressure (ICP) in four cases of pseudotumor cerebri, a volumetric rather than a pressure-dependent device was proposed to drain a given amount of cerebrospinal fluid at each maneuver by external finger pressure according to preoperative ICP recordings. Some of the advantages of this method are discussed.

5-Fluorouracil, adriamycin and cyclophosphamide combined with high-dose medroxyprogesterone acetate in advanced breast cancer.

Seventy-six patients with metastatic breast cancer were treated with fluorouracil, adriamycin (doxorubicin) and cyclophosphamide (FAC) plus high-dose medroxyprogesterone acetate (HD-MPA). MPA was given for 21 days at the dose of 500 mg/day i.m., then on a randomized basis, either 500 mg/week i.m. (FAC+HD-MPA i.m.) or 300 mg/day p.o. (FAC+HD-MPA p.o.). Objective response rates were 79% in 39 patients on FAC+HD-MPA i.m. and 73% in the 37 patients on FAC+HD-MPA p.o. There was no significant difference in the median duration of response and median survival for the 2 regimens (respectively, 17 months and 22 months, and 15 months and 21 months for FAC+HD-MPA i.m. and FAC+HD-MPA p.o.). Toxicity was mild and similar in both groups. Although FAC+HD-MPA was highly effective, at present it is difficult to select which regimen provides the best initial treatment for metastatic breast cancer.

Paclitaxel activity in anthracycline refractory breast cancer patients.

AIMS AND BACKGROUND: We investigated the efficacy and tolerability of two doses of paclitaxel, 175 mg/m2 and 135 mg/m2, over a 3-hr infusion, without prophylactic G-CSF, in heavily pretreated patients with anthracycline-resistant breast cancer. Although paclitaxel may share with anthracyclines a common mechanism of drug resistance, there is evidence that the two drugs are not completely cross resistant. METHODS: From July 1994 to January 1996, 42 patients were treated every 3 weeks, for a maximum of 6 cycles; paclitaxel dose was established according to pretreatment extension. RESULTS: In 41 assessable patients we observed 9 partial responses, for an overall response rate of 22% (95% CI, 10-34%). There was no difference in response rate between the two dose levels. Median duration of response was 9 months, median time to progression 5 months, and median survival 9 months. The dose-limiting toxicity was neutropenia, which was grade 3-4 in 40% (135 mg/m2) and 62% (175 mg/m2) of the patients (P = 0.28); neutropenic fever occurred in 24% of the patients, without significant differences between the two dose levels. Other toxicity was mild to moderate. CONCLUSIONS: Paclitaxel at doses of 175 mg/m2 or 135 mg/m2 is active and well tolerated in advanced breast cancer patients resistant to anthracyclines. The prophylactic use of colony-stimulating factors seems appropriate in heavily pretreated patients given the higher dose level.
